ERCC1 and glioma: In a study on adult glioma cases and controls in a Caucasian population, it was presented that patients with oligoastrocytoma were significantly more likely to be homozygous in ERCC1 C8092A polymorphism than the controls (CC versus CA/AA: OR = 4.6, 95% CI: 1.6–13.2), however, no significant results were found in other histologic types of glioma [16].
